    I had braces when I was in HS but failed to wear my retainers. My teeth started to reverted back to its original position. My two front teeth were starting to curve outwards, it was becoming obvious in pictures (side profiles). When I was talking you could see how crowded and crooked my bottom teeth were. An ex called it my "snaggle tooth". But what finalized my decision to get Invisalign was when my dentist suggested it as an option to correct gaps that started to form between my teeth. Every time I ate food would get stuck between my teeth. Not good conditions for oral health. Especially for someone like me who was at risk for getting cavities between teeth. My dentist (who is the best) highly recommended Dr. Masaki (who is also the best). He educated me on the importance of going to an Orthodontist even when he himself had been an Invisalign provider in the past. Dr. Masaki and her team are amazing. I was given the best care by her and her team every time I walked into her office. Appointment scheduling was tight but organized. I was always called when an opening came up to get in at in earlier date. Parking is easy, quick and reimbursed. Shout out to her front desk staff (Nicole?). I am sure it is stressful to be answering the phone, making apts, etc, but I was ALWAYS greeted with a smile when I entered the office. Plus, you get free tooth brushes, tooth paste, tray cleaners, etc at every visit for checking in to social media platforms. Dr. Masaki never cut corners. I had multiple extensions to my treatment plan in order to get the very best outcome. Mostly importantly she made sure my gaps were fixed. The proof is in the pudding because as you can see my teeth are PERFECTION! Dr. Masaki's prices are very reasonable for Hawaii. There are zero interest payment plans that are helpful as well. I know other dentists on the island do offer cheaper prices but I will say that your oral health is something worth investing in. Cheaper and faster isn't always best, it can cause dental problems that will cost you more in the future. You can forget companies like Smile Direct. Don't do it. Thank you, Dr. Masaki and team for bringing my smile back to life!

    Doctor and everyone are awesome! They are all so sweet and understanding and very atheistic whenever I come for an appointment.

    Guess who got her braces off?! I'm so incredibly grateful for Dr. Masaki and her AMAZING team. They've been so accommodating especially with my schedule and my goals with my smile. I love my new smile so much and I'm glad I found you! I've had my braces on since November of 2020 and I gotta say as much as I miss them, I'm so happy to have them off haha. This was such a confidence booster, worth the time and money. I sound like a broken record but I couldn't be happier. Bittersweet moment because I love catching up with you guys and seeing you routinely every 6 weeks LOL! Super efficient staff, friendly, and the best at their jobs! I'm getting all emotional but anywho, IF YOU OR YOUR LOVED ONES ARE LOOKING FOR AN AMAZING ORTHODONTIC TEAM-- GO HERE!! And let them know I sent you ;-) hahaha. Thank you folks so much for the care and support and the friendship!! I LOVE YOU GUYS!

    We LOVE Dr. Masaki and her awesome Team! Convenient location, great workmanship, reasonable prices, and caring & friendly staff! We have full confidence in her, trust her knowledge and expertise, and know that she puts her patients' best interest first! We feel important, valued, and well taken care of! Thank you for everything!!! And on a side note, we also LOVE THE goodies we get when we check in for our appointments! It's like the "old school" treasure chest but soooo much better! I picked up this cute eraser and a pencil sharpener at today's appointment! Gotta love it!

    My daughter goes here and we really do enjoy it. The staff is very friendly and the atmosphere is very cute and beach themed. The office always looks perfectly clean and I especially liked that they were the cheapest place by far. They were also willing to work with us on price (my daughter came here with braces already on) which I appreciate greatly because as we all know EVERYTHING is expensive here. I would recommend this place to a friend anytime, the money and time they saved me is worth it

    My teeth are so straight! Thanks Dr. Masaki and staff!

Kim Orthodontics strikes a rare balance between advanced technology and genuine, high-touch care, making the whole orthodontic experience efficient--and, dare I say, even enjoyable. The usual frustrations you might expect with medical offices--long waits, mysterious surprise charges, parking hassles, or difficulty scheduling--just aren't an issue here. The self-service scanning technology eliminated the need for frequent visits, as everything was handled online. Communication via their app and text was excellent. The staff is top-notch and the office clean, modern, and sleek. Our son needed his teeth straightened, and Dr. Kim and the entire team did an outstanding job. His treatment recently wrapped up, and we couldn't be more pleased with the results. Even better, since not all of his wisdom teeth have come in yet (though there's room for them), they've arranged for thoughtful post-treatment follow-up. In short, we highly recommend Kim Orthodontics.

Also I am not hired by anybody by writing this review. Some people might think sounds too extremely great and good to be true However... Everything here is based on real experiences. Please enjoyed reading my amazing experiences with dr Tammy and team! Before writing this review, I would like to share something important. Over the past 10 years, Dr. Tammy Chang has done more for me than I could ever fully express in words. Even with so many patients, she always takes the time to truly see each individual and treat them with genuine care and compassion. There were times in my life when I was going through very difficult periods. During those moments, visiting her clinic was never just a routine appointment. Her words and the way she treated me were never superficial--they were sincere and heartfelt. Every time I left, I felt encouraged, thinking, "I'll do my best until the next time I come back." She gave me hope exactly when I needed it most. Not only did my smile become more beautiful, but I also remember how my emotional well-being gradually improved throughout the orthodontic process, almost as if my mind was being aligned along with my teeth. Some people might feel that sharing something like this is too much. But I truly felt that her kindness came from a genuine place. In the end, she didn't just improve my smile--she helped restore my emotional strength as well. After my recent visit, I felt a strong desire to do something for her, so I asked if I could write this review. Although she is very humble and had never asked patients for reviews before, I could clearly feel how much it meant to her. That is exactly why I decided to write this. Everything here is based on real experiences--my own and those of people I know who have also been treated by her. This is not for marketing, but simply to share the truth. I have been a patient of Dr. Tammy Chang for many years, and I can say with complete confidence that she is not only an exceptional orthodontist, but also an extraordinary human being and leader. What truly sets her apart is her deep compassion. She treats every patient with kindness and respect, and I have never met a doctor with such a warm heart. You can feel this the moment you walk into the office. The front desk team greets you with genuine smiles, creating a warmth I have never experienced in any other clinic. You can also sense how much the staff trust and appreciate her. The entire clinic is filled with positivity. The interactions between staff and patients are so warm that it almost doesn't feel like a medical office--you simply feel happy being there. Even after not visiting for nearly five years, when I returned, each staff member came up to me personally to greet me and reconnect. That level of care is truly rare. In today's world, many clinics rely on marketing and social media, but Dr. Tammy's clinic is different. Her practice is built on trust, real quality, and genuine care--patients naturally refer others. That is exactly how I found her, and why I now recommend her with complete confidence. Dr. Tammy truly deserves to be recognized at the highest level. Thank you Dr and stuffs member! Arigatou! 《日本語バージョン》 } Dear Dr. Tammy, I hope you are doing well. I wanted to share something from my heart. 私は10年以上、Dr. Tammy Changの患者としてお世話になっています。 彼女は矯正歯科医として優れているだけでなく、人として本当に温かく、思いやりのある方です。 人生の中で辛い時期にも、彼女の言葉や存在に何度も支えられてきました。 歯並びが整っただけでなく、気持ちの面でも前向きに変わっていったことを強く実感しています。 クリニックの雰囲気もとても温かく、スタッフの皆さんも優しく、安心して通うことができる場所です。 今の時代、多くの場所がマーケティングに頼る中で、彼女のクリニックは「信頼」で成り立っていると感じます。 だからこそ、私は心から自信を持って彼女をおすすめします。 Thank you for everything.

I dont really give out reviews unless I find it necessary. That said, I only do so when it's bad service. When I told them it felt off, the doctor fixed it on the OPPOSITE side of where I told them, which wouldn't be a problem, but when they fixed it on the right side, it added up so ultimately it still had the same issue. Not only that, the person who was taking care of me [i didn't get her name] pinched my lip pretty hard between the braces wire and the brackets. When I reacted the first time, it hurt pretty bad. I was still a little worried when she did it again, because she pinched it a few times and it stung a bit while she put it on, I flinched. She seemed kind of annoyed at that. I felt uncared for and like they didn't care about my comfort and needs. Now I look at it, it's really uncomfortable to "rest" my mouth to look normal, and when I actually rest it the "build up" is what they called it, forces my mouth to look crooked due to uneven amounts on each side. It's slightly unclear in the photos, but it's more clear if I had gotten them from the same angle. Other than that normally it's better service, so hopefully it'll get better again with time with this new doctor, but I'm not a fan of it so far.
